COMBINED SAW-SET AND PUNCH.

SPEGIPLCATION forming part of Letters Patent No. 387,133, dated Jul 31,1888.

(No model.)

To all! whom it may concern.-

Be it known that 1, WILLIAM G. AVERY, a citizen of the UnitedStates,residing at Cleve land, in the county of Guyahoga and State ofOhio,have invented a new and useful Improvement in a Combined Saw-Setand Punch, of which the following is a specification.

My invention relates to an improvement in the saw-set and punch patentedto me by Let ters Patent No. 282,600, dated August 7, 1883. The saw-setand punch covered by said Letters Patent are provided with a hollowpunch adjustahly fixed near the end of the jaw O to be used when desiredfor punching leather. The punch is held in place by a set-screw, so thatthe punch may be taken out and reversed in positioni. 6., the pointturned up from said jaw when not required for use. It is also providedwith a thumb-screw to pass through said jaw O at a point between saidpunch and the die D for use in gaging the throw of the said die when thetool is used forsettinga saw.

This invention is a thumb screw bored through its length, so that it maybe used in connection with said tool either as a punch or for gaging thethrow of the die D in setting a saw. Its object is to simplify said tooland cheapen its manufacture by doing away with the separate thumb-screwgage and the hollow punch with its set-screw.

In the accompanying drawings, Figure 1 is a side elevation of a combinedsaw-set and punch containing the improvement herein set forth. Fig. 2,isa longitudinal section of the within described hollow thumb -screw, andshows its use in connection with the grippingjaw O.

The thumb-screw E is round, made hollow,

as shown in Fig. 2,and is tapered to a cuttingedge at its lower end, andis threaded to pass through a cylindrical threaded hole made in thegrippingjaw, O, as shown in the drawings. Said hollow thumb-screw E maybe adjusted as desired for gaging the throw of the die D in setting asaw, or it may be used for punching leather, paper, and other articles.

The drawings so fully exhibit the invention herein claimed that nofuller description of the same or of its construction and operation isneeded than what is set forth.

The anvil-jaw A,With its chambered handle, having the ears (I and thesprings, the adjustable gage g, the lever-handle B, and the moveablegripping-jaw 0, having a die, D, are no part of this invention and arenot claimed herein. The combination with the jaw (J of the saw-set, andof a common cutting-punch adjustably fixed and held with a set-screw forpunching leather in conjunction with the jaw A, is also a part of theinvention covered by said Letters Patent No. 282,600, and is not claimedherein.

Having fully described my invention, what I claim as new, and desire tosecure by Letters Patent, is i The combination, with the saw-setconsisting of the anvil-jaw A, with its chambered handle, having ears dd and spring .9, leverhandle B, and the movable gripping-jaw 0, havingdie D, of the screw-threaded hollow punch E, substantially as setforth,and for the purpose specified.
